This is an update from the customer 4/2023 after months of rain!

Hi James.

You transformed our crawlspace a couple years ago and I wanted to give you an update. We had the mother of all rainy winters this year, yet we had zero issues with water or odors under the house. Your work saved us tens of thousands of dollars and disruption had we instead added a French drain as we originally contemplated (which wouldn’t have addressed the odors anyway). So Patricia and I want to thank you again for doing such a nice job here.

Take care, and feel free to stop by any time if you’re in the neighborhood.
